The Civil War Sesquicentennial has increased the pace of digitization of historical artifacts. Of course these projects will never be complete — there is always more to find when visiting a library, museum, or archive — and of course there is a difference between having a historical document, sculpture, or artifact in your hand, rather than viewing it online.

And the blog of the Missouri State Genealogical Association has great leads on city directories, house histories, cemetery indexes, and more. (Attached here is a list of those mentioned in the book buried in Bellfontaine Cemetery, thanks to Jerry Garrett.)

Below are links to documents essential to the writing of The Great Heart of the Republic, organized by the book chapter for which they are most relevant. I invite you to read the original sources, and to continue the crucial study of St. Louis within the West, the North, and the South during the Civil War Era. (These are only manuscript and visual sources; for those published as books, there is near-complete coverage in Google Books.)

Please contact me with any questions, and as you find other sources online.
